4. Write a decimal for each of the following. Use a place value chart to help, if necessary.
a. 7x10 + 4 x1+6x (1)+9x (100) +2x (1000)
b. 5 x 100 + 3 x 10 +8 * 0.1 + 9 0.001
c.
4*1,000 + 2 x 100 +7x1+3+ (109) +4x (1000)

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

ok then what happened.

my answer got deleted but it's a

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
